PHP Cookies

A cookie is often used to identify a user. A cookie is a small file that the server embeds on the user’s computer. Each time the same computer requests a page with a browser, it will send the cookie too. With PHP, you can both create and retrieve cookie values.

Create Cookies

setcookie() method contains different parameters but in the below example we will only use 4 parameters, Cookie Name, Cookie Value, Time in Seconds and Path.

Copy Code


<?php

	$cookie_name="color";
	$cookie_value="black";
	
	setcookie($cookie_name,$cookie_value,time()+86400,"/");
	
?>

Read Cookie

	if(isset($_COOKIE['color'])){
		echo $_COOKIE['color'];
	}else{
